Letters Patent No. 73,081, dated January 7, 1868-.

IMPROVEMENT-IN UULT IVATOR AND PLOUGH.

TO ALL WHOM IT MAYCONOERN:

Be it known that-we, WILLIAM H. DAMRON, Rorsnr H. MASSEY, and LorenzoF.-WH ITMAN, of Macomh, in the countyof McDonough, and State ofIllinois, haveiuvented a new and improved Cultivator andP-loughj and wedo hereby declare that the following is a full and exact description ofth'e some, reference being had to the accompanying drawings, and to thelettersof reference marked thereon.

This invention consists chiefly of devices for render ing tho beams andsupporting-wheels of a cultivatingmachine adjustable laterally, in s uchmanner as tooonvert the apparatus into a gang or subsoil 'pl'ough, aswill hereinafter more fully appear.

To enable others to make and use our inventionpwe'will now proceed todescribe its construction and operation. 7 I v A represents theframework of the m'achine,'o'f ordinary construction, supported by meansof the wheels a a connected with the cross-bar a, and the caster-wheelsb 6 secured to the front endsof the 'pl'ough beams o a. The saidplough-beams run longitudinally-of 'the frame-A, and to them are pivotedthe plough-shanks e, which are susceptible of elevation and depression,inthe usual manner, by means of theieverdand rack '02. The wheels in arevolve on axles projecting from the lower ends of wrists e e, Figure 3,which are connected with the crossbar a by means of sliding chases e, insuch manner that the said wheels are laterally adjustable onthe crossbara", andmay be fixed at any desired points thereon-by means ofset-screwsIt 7 operating in connection with one of each pair of the'chases e. Thepurpose of making the wheels thus adjostable is that they may both beset on-the same side of one of-the -plough-bea'ms, the other plough-beambeing removed, and the cultivator thus turned into a gang-plough, in theoperation of which the wheels will run on the unbroken ound. The. rearends of the plough-beams cc are'sus'tained in the crotches f 2', whichare also adjustable on the cross-bar a, in like manner. as the chases e.Said crotches are pierced with horizontal holes 1", in the direction ofthe length of the cross-b ar ai, by'means of which-holes and the pins71%, the rear ends of the ploughbcams may be set at various heights. Thefront ends of the ploiigh-beains c c are also embraced .by crotches Z Z,the shanks Z Z of which pass vertically i pward through correspondingorifices m, Figure 2, in the projecting flanges on of the guide 11.,that reciprocates horizontally in the slot 11/ of the front cross-beam 0of the frame A. The shanks Z4, may be shiftedin the orifices m', -as mayhe desired. The advantage of making the ploughbea-ms thus laterallyadjustable is at least twofoldz first, the ploughs may be made to throwdirt to or from the plants by simply shifting the beams to the sidesopposite those where they are represented in the drawings;

second, the beams may be set-without the side picces'oi' the frame, andthus made to throw dirt against trees 7 or other vegetable growths toohigh to be straddled by the machine. By making them verticallyadjustable, if both ploughs are placed on one side, and near therearlend of the beam, and the latter letdown in the crotchcs e e, asubsoil plough is obtained.

I It will be observed that the ploughs are made with cutting-edges 7'projectingsorne distance forward of their curved sidos. These edges arefor the purpose of making'a smooth out, so that none of the soil shall,by

them, be thrown to either side to the injury of the plants. They alsoact asfenders t-o prcventclods from passing over the front edge of theplough upon'th e plants. The guide we is operated by the levers,-pivoted toone of the cross-beams of the frame. 7

Having th s fully described our invention, what we claim as ncw,,anddesire to secure by Letters Patent, is-

1. The combination of the wheel a with the wrist .e, sliding chases e,and cross-beama, as and for the purpose described. 7 H

2. The combination of the plough-beam c with the sliding crotches z',the cross-beam a, the guide at, and slotted cross-beanie, substantiallyasset forth. I

3. The combination of the plough-beam c withthe crotches z, providedwith thohoies iand pins 70, as and for the purpose set forth. 7 v pWILLIAM H. DAMRON, I ROBERT H; MASSEY, Witnesses: LORENZO F. WHITMAN.
